订单的PHP脚本放在哪里？
大家好，我使用dreamweaver，我一直在学习本教程 关于PHP脚本放在哪里的细节不是很具体，所以我不知道应该放在同一页还是另一页。我有orfm.php，其中包括用于计算的订单和javascript。这很好。单击submit按钮后，该操作将导致submited.html。但是在同一页面上添加了用于在mysql中插入数据的PHP脚本orfm.PHP之后，它就不能正常工作了。我应该把它放在另一页上，还是我在同一页上的位置有误 以下是脚本：订单的PHP脚本放在哪里？,php,mysql,database,insert,dreamweaver,Php,Mysql,Database,Insert,Dreamweaver,大家好，我使用dreamweaver，我一直在学习本教程 关于PHP脚本放在哪里的细节不是很具体，所以我不知道应该放在同一页还是另一页。我有orfm.php，其中包括用于计算的订单和javascript。这很好。单击submit按钮后，该操作将导致submited.html。但是在同一页面上添加了用于在mysql中插入数据的PHP脚本orfm.PHP之后，它就不能正常工作了。我应该把它放在另一页上，还是我在同一页上的位置有误 以下是脚本： <? //uncomment for debug

在没有看到标记/html方面的情况下很难做出判断，但这里有几个要点：
- 您可以使用
在标签的action属性中，或转到另一个页面htmlentities（$\u SERVER['PHP\u SELF']）将页面提交给自己action=“submitted.php” - 确保输入区域
属性名称与大小写匹配。如果您在文章后面的脚本中有name=
，那么$\u POST[“test”]并不是您想要的确切答案，但是PHP初学者应该知道一些事情- 您的代码包含一些不推荐使用的组件
- 您的代码缺少
- 您的代码缺少。HTML、CSS、业务逻辑、表示逻辑等都在一个文件中
- 开始使用一个好的IDE，比如
- 使用一个好的调试工具，比如XDebug
- 最后，开始使用一个好的框架，比如Zend、CakePHP CodeIgniter Symphony或其他数千个框架中的任何一个。几乎所有的框架都在其入门指南中包含表单到数据库
'eddata@MichaelColeman那么，我应该将php脚本粘贴到submitted.php上吗？@MichaelColeman它现在使用submitted.php。我把php代码放在那里，它给了我很长的错误。我会编辑我的帖子，你能提供包含表单的HTML吗？谢谢，您提供的php脚本的文件名是什么？虽然我很想在这里发布所有内容，但它不允许发布太多代码：（我会读你的这本书，谢谢。POST<form method="POST" action="submitted.php" onsubmit="return Validate(this)" name="ofrm"> <p>Please tell us who you are (<font color="#FF0000">red</font> denotes required information):</p> <table border="0" cellpadding="0" width="550" id="table1"> <tr> <td width="340" align="right"><font color="#FF0000">Name</font></td> <td width="10"> </td> <td width="200"><input type="text" name="Name" size="30" tabindex="1"></td> </tr> <tr> <td width="340" align="right"><font color="#FF0000">Email</font> (Your confirmation will be sent here): </td> <td width="10"> </td> <td width="200"><input type="text" name="Email" size="30" tabindex="1"></td> </tr> <tr> .......//more here <td> <input type="submit" value="Submit" name="subButton" tabindex="50"> <input type="reset" value="Reset" name="resetButton" tabindex="50"> </td> </tr> </table> </form>\n"; echo "Please check the following error messages carefully, then click back in your browser."; echo " \n"; while(list($key, $val) = each($error)) { echo $val; echo " \n"; } //stop everything as we have errors and should not continue exit(); } //we do not need the rest of the form fields as we can just calculate them from the whole numbers if( !empty($_POST["qtyA"]) ) { $qtyA = $_POST["qtyA"]; $totalA = $qtyA * 1.25; } else { $qtyA = 0; $totalA = 0; } if( !empty($_POST["qtyB"]) ) { $qtyB = $_POST["qtyB"]; $totalB = $qtyB * 2.35; } else { $qtyB = 0; $totalB = 0; } if( !empty($_POST["qtyC"]) ) { $qtyC = $_POST["qtyC"]; $totalC = $qtyC * 3.45; } else { $qtyC = 0; $totalC = 0; } $GrandTotal = $totalA + $totalB + $totalC; //we can store the order in a database as well $link = @mysql_connect('localhost', 'root', 'password'); if (!$link) { echo "Could not connect: " . mysql_error(); } else { mysql_select_db('admin'); $query = "INSERT INTO order_queue ( Name , Email , OtherInfo , qtyA , totalA , qtyB , totalB , qtyC , totalC , GrandTotal )"; $query .= " VALUES ('$Name', '$Email', '$OtherInfo', '$qtyA', '$totalA', '$qtyB', '$totalB', '$qtyC', '$totalC', '$GrandTotal')"; //echo $query .
